COLLECTING DEVICE.

application Afina sept-embel- TQ all 'whom it may concern.'

Be it known that I, Leurs CHARLES Rinse, residing. at Saginaw,` Michigan, have in' vented a certain neu7 and useful improvement inV Collect-ing Devices, of `which the following is a clear, full, andeXact description. i i

rlhis invention relates to devices for collooting and conserving materials which might otherwise be Wasted in manufacturing operations, and is herein shown as e1nbodied in a device Yfor collecting flour or other material that `falls from the rotating tablev of a douglrmolding machine of the type in which the dough pieces are molded into shape by being passed between a .revolving table and a stationary trough arranged spirally about the active surtacejoi the latter. It Will be understood,however, that the invention `is not restricted to the illustrated embodiment or usesy and that many features of the invention are of general utility.

`An object of the invention is to provide a device iforcollecting and conserving mate rials, Which may be attached, to a machine such, for example, asthe doughanolding machine herein illustrated and Which will operate substantially automatically. c

A further object of the invention is so `to arrange the receiving and gathering elements of the device or its attachments as to take advantage of the movement of parts of the machine With which it is associated. An, important teinture of the illustrated en'ibodiment ot the invention, in which a'. stationary receiving trough. is arranged to receive the flour or other material dropping from a circular rotating table, is the connection to the rotating table or a collecting dc` vice (herein shown as a brush or sweeper) whereby the material droppingfinto the receiving trough is gathered together and moved to a common discharge point.v

Another important feature of the invention isthe arrangement of the point of discharge, and a suitable receptacle for receiving the material gathered by thebrush or other gathering .means7 directly beneath the point at which the greater part of the materiahthe collection of which is the purpose oit' the present invention, is delivered to the rotating table, thereby permitting any excess amount ot this, or any part et it whichv tends to drop directly from the table, to be in nnediately received into the collecting box "mechanismg Y e, 1924. serial no. reame.

or other suitable means for` receiving and conserving the material.

Other objects and important featuresy of nthe invention Will appear frOmthe-ollow# ing description and claims when considered in connection With the accompanying drawings, in which Fig. 1 is a cross sectional side view of such a dougl'i molding machine;

Fig. 2 is a plan View of thetable thereof showing the flour catch and its associated Fig.` 3 is a view of the trough taken through the line 3-3 in Fig. 1 and showing the sweeping mechanism; and

Fig. l is a view of the sweeping mechanism taken trom the line 4-t in Fig. 3Q

rlhe dougli-1nold-ing imachine shown in Fig. 1 comprises a molding table 1 rotatably supported by an annular roller bearing 2 mounted on a bracket 3 formed about a col` umn el on which the molding lmachine rests. `The table is rotated by means of a gearing 5 driven by an electric motor 6. The gearing and the motor are carried by an annular bracket 7 fixed about the middle of the column 4Q A molding trough 8 spirally arranged about the table 1 is removably suspended from adjustable links 9 extending from the rim. of a `Wheel 10` carriediby a head block 11 on the column Ll. A. flour sprinkler 12 is suspended by a bracket 14k :from the wheel 10. This sprinkler consists ot a l'lour box 13 having a halt cylindrical perforated or slit bottom and et a rod agitator 15 lined to a shaft 1 8 whichis pro-` vided with a pinion 17 meshing with au annular toothed ring le i'iiounted ou the flat annular top of the table 1. A trough 19 resting on standards 2O lined in the floor and a box 21 supported by a bracket 22 upon annular brackets 7 provide a catch `for the flour thrown ofi by the table. The trough 19 has a bottom part of semiecireular cross sectional form and said trough receives the peripheral edge of the table Which projects belen7 the top ot' the trough, the side Walls of the trough being raised higher than to a point above the peripheral edge of the table. As shown, the side Wallunderneath the table is vertical and the outer Wall is inclined ina direction avvayfrom the table.

A sweeper 23 is attached to the rim of the rotating table 1 and drives the Waste collected therefrom in the trough 19 into be;`

fio

2l. The trough is so shaped that when the sweeper is at work there will be no likelihood that dust will be stirred up by its action nor that any particle of flour pushed before the same will rise over the top ot the trough. rlhe end 24 of the trough is connected to the rim of a corresponding incision in t-he end wall 25 of box 2l by a flange Q6, and the end 27 ot the trough to the rim o'lE a corresponding incision in the end wall 2S by a flange 29. ln the bottom of the box Qi is a shutter 30 worked by means oit a. handle 3l. A`\."\lhenever a. sul'licient quantity ot i/lour has accrunulated in the box 21, the shutter 30 may be drawn open whereupon the flour contained in the box is dropped into a suitable receptacle and taken away.

The sweeper' illustrated in Figs. 3 and l consists ot a brush comprising bristles and a back 33. The back 33 is shown as inclined in the direction of rotation ot the table at an angle of about ao. The bristles 32 are so mounted in the rim of' the back 33 se as to point vertically toward the inner suriace of the trough 19 and to sweep the same up to the height of the lower surface of the rim 34 otl the table l. An elongation 35 on the back 33 extends upwardly across that portion ot the trough not covered by the table. The back 33 is provided with a handle 3G whose top 37 is adapted to tit in a corresponding recess 38 in the rim 34rof the table. Member 37, which is curved to conlorm with the curve of the rim 34, is held in the recess 3S by means of a bar 4:0 preferably made ot a resilient material such as springy steel. This bar is rotatably mounted at one end by means of a screw 4l to the rim Itis provided at its opposite end with an incision 42 which lits over a set screw elfi in the rim 34 beyond the other end ol` the recess winged nut i3 upon screw -fl-ll serves to tighten the bar against the top 3T o'll the brush handle 3G and thus to .keep the latter in its operative position. ln order to secure the member 3T as lirnily as possible in lthe recess 3S, it is preferable to place a suitable packing 415 ot India rubber, cardboard, or the like, at the back ot the recess 38. It the bristles 32 have been worn away so as to necessitate the adjustment of the brush a packing 46 of the required thickness may be put between the top ot the recess 38 and the top ot the bar 37.
